I didnt follow the standards as far as a car pc, and I havent had so much as a glich. I went with a computer pull from a job. Its a Compaq Evo 1.5ghz. It has a power on upon power restore, so I didnt have to have a shutdown or startup controller. I run it, and all other accessories, off of a power invertor. I have a gig of pc133 ram. I went with a regular 120 gig hard drive, 5.25 size. An ATI video card with s-video and rca output, as well as the vga. I chose a Xenarc monitor, without a touchscreen. Check my site for the rest of my specs, and pictures of it all, and install. Feel free to contact me with any questions, comments.
